Are you a disgruntled employee? You sure sound like one. That, plus that you worked there over ten years ago - and that Rackspace didn't even offer a DNS api until a few years ago[1] - makes it very hard to take seriously any of your claims about the nature of their dns infrastructure. All we know is that Rackspace has dns servers in three out of its six datacenters[2], and that they appear not to have always-on DDoS protection in place. Market cap and technical sophistication, esp at large scale, tend to become divergent. You say this, but go on to compare Rackspace unfavorably to Amazon who, at 141.93B (of which AWS is just a part), has over 20x Rackspace's market cap and probably 10x the infrastructure[2][3]. Big companies do things poorly, but then it's hard to have highly-available dns without having lots of infrastructure. Namecheap, Route53, Dyn, DNSimple, and now Rackspace have suffered DDoS attacks with outages of varying severity. Don't act like DDoS prevention is a solved problem and claim technical incompetence. 1: http://www.thewhir.com/web-hosting-news/web-host-rackspace-offers-cloud-dns-beta-to-uk-and-us-customers http://www.thewhir.com/web-hosting-news/web-host-rackspace-o... 2: http://www.rackspace.com/about/datacenters http://www.rackspace.com/about/datacenters 3: http://aws.amazon.com/about-aws/global-infrastructure/ http://aws.amazon.com/about-aws/global-infrastructure/
